Uncaught Error: Canvas is already in use.

    I’m using a list of Donut Charts to be rendered in a single page (6 donuts to be exact), I’ve used the respective shorcodes generated from Visualizer and when I visit the single page for the first time the charts are displayed correctly, however when the page is reloaded the charts aren’t being displayed and a javascript error is gotten in the console with the following statement:

    Uncaught Error: Canvas is already in use. Chart with ID '0' must be destroyed before the canvas can be reused.

    When I try to reload the page, sometimes charts are displayed and sometimes not, however the js error persist in the console.

  • Hi @alejandromarin,

    Thanks for choosing Visualizer!

    I tried to replicate this on my instance but everything is working properly for me. I’ve added 6 donut charts on a page and even more than 6 on another and I don’t get any errors, the charts are properly displayed for me. Please provide us the URL to a page where we can see this issue.

    Thank you!

    @luciamarinescu Here is the URL to check the issue: https://fortnightcodev.wpengine.com/diversity please use following credentials for the prompt: demo /codelab303Rocks!
    If you visit that page, you’ll see the issue happening, as I already mentioned charts are correctly displayed at the first time, but if you reload the page for second or third time the issue will appear, I’m suspecting something is failing in Visualizer when the canvas are already loaded for the first time and they aren’t not initialising again in the next page loading.
    Please let me know if you need more details to dig into it.
